What's the difference between jQuery $().each() and implicit iteration? -

-

i have 2 inputs 2 separate search forms of same page. 1 has data-result-select-url attribute , 1 doesn't.

<input id="q_id_eq" class="foo" type="text" size="30" name="q[id_eq]" data-result-select-url="/products/(id)" tabindex="-1"></input>  <input id="q_id_eq" class="foo" type="text" size="30" name="q[id_eq]" tabindex="-1"></input>

i write own select2 plugin these inputs.

$ = jquery $.fn.my_select2 = (args) ->   ...   select_url = $(this).data("result-select-url")   if select_url?     $(this).on "change", (e) ->       ...    $(this).select2 args

when use $().each() call plugiin my_select2(), works fine. 1 input receives "changed" event.

jquery   $('.foo').each ->     $(this).my_select2()

but if call my_select2() using jquery implicit iterations, both inputs receive event.

jquery ->   $('.foo').my_select2()

what explanation? looked jquery doc each couldn't find answer.

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
